Proof of work
The team
Founded in 2011, Kraken is one of the world's longest-standing crypto platforms, trusted by over 10 million individuals and institutions across the globe. It offers spot trading, margin, futures, staking, and OTC services, with products built for both individual investors and institutional clients.
The AI Infrastructure team builds and operates the production systems that power intelligent agents at scale. This team sits at the foundation of the agent platform, ensuring that model inference, orchestration, and execution layers are reliable, observable, and performant under real-world load.

Implement and maintain streaming systems using RisingWave, Apache Flink, or Kafka Streams, selecting the right tool for the workload
Partner with ML engineers and AI infra teams to define data contracts, feature schemas, and pipeline SLAs
Drive pipelines toward real-time where batch exists today reducing latency from hours to seconds
Ensure data quality, observability, and auditability across all streaming and feature engineering systems
Contribute to inference pipeline tooling where data engineering and model serving intersect
Evaluate emerging streaming and feature store technologies and shape the team's technical roadmap
What You Bring
5+ years in data engineering with at least 2 years focused on streaming systems in production

Experience building data pipelines that feed production ML models or inference systems
Proficiency in Python and/or Scala; SQL fluency required
Familiarity with data quality frameworks, pipeline observability, and SLA ownership
Comfortable operating in a fast-moving, ambiguous environment embedded within an AI-focused team
